Graph of Hyperbolic Sine Function

Plot Hyperbolic Sine and Exponential Functions

The hyperbolic sine satisfies the identity sinh(x)=ex-e-x2. In other words, sinh(x) is half the difference of the functions ex and e-x. Verify this by plotting the functions.

Create a vector of values between -3 and 3 with a step of 0.25. Calculate and plot the values of sinh(x), exp(x), and exp(-x). As expected, the sinh curve is positive where exp(x) is large, and negative where exp(-x) is large.
